The Tory politician appeared on the show to debate the age of child refugees - but Piers made it very clear that he was not a fan of David's views.

Piers left the right-wing politician red-faced as he lambasted his view that migrants should be forced to have their teeth inspected before being allowed to enter the country in a bid to prove they're under 18.

He told the politician: "Who are you to decide that these very impoverished people who have been through a hellish time and are coming to this country in small numbers should have their teeth checked?"
